Select from our enterprise-grade portfolio of valve-integrated pouches, high-barrier Mylar films, and specialized drip coffee paper packaging.
As a specialized manufacturer and supplier of custom coffee bags with valves, YPAK Packaging Group combines material science, optical print tech, and Swiss degassing valve integration to deliver high-barrier packaging solutions. Engineered for micro-roasters, commercial brand owners, and multinational co-packers, our flexible packaging preserves aromatic volatiles, prevents oxidation, and elevates shelf presence.
Every fresh roast releases significant CO2 gas. Standard one-way degassing valves from WIPF (Switzerland) are heat-sealed directly into our laminate matrices, providing immediate pressure relief while maintaining absolute atmospheric isolation against ambient oxygen and moisture ingress.
Our advanced manufacturing facilities in Foshan and Dongguan maintain BRCGS Food Safety Grade AA and ISO 22000:2018 certifications. Every production run undergoes automated visual inspection and continuous seal-strength validation for food-grade safety.
Equipped with the HP Indigo 25K digital press, YPAK eliminates cylinder plating costs and high minimum order quantities. We provide photorealistic printing, perfect spot color matching (Delta-E < 1.5), and short turnaround times for limited-edition roasts.
Freshly roasted specialty coffee beans undergo an intense off-gassing process, releasing up to 10 liters of carbon dioxide (CO2) per kilogram over a 14-day post-roast window. Without a functioning one-way degassing valve, hermetically sealed pouches balloon and rupture. Conversely, non-valved or poorly valved packaging exposes whole beans to ambient oxygen, triggering rapid lipid oxidation, degradation of delicate volatile aromatics (such as furfurylthiol and pyrazines), and staling within 72 hours.
| Performance Parameter | Standard Generic Valve | WIPF Swiss One-Way Valve (YPAK Standard) | Impact on Coffee Flavor & Shelf Life |
|---|---|---|---|
| Opening Pressure Threshold | 10 - 20 mbar | 2.0 - 5.0 mbar | Prevents bag distortion while venting CO2 instantly post-roast. |
| Closing Pressure Threshold | Variable / Inconsistent | 0.5 - 1.5 mbar | Ensures immediate seal closure, preventing ambient air backflow. |
| Oxygen Ingress Rate (O2 Transmission) | > 0.5 cc/valve/day | < 0.01 cc/valve/day | Extends specialty roast freshness from 4 weeks to 18+ months. |
| Diaphragm Membrane Material | Recycled Rubber / Low-Grade Silicone | Food-Grade Silicone Membrane with Filter Screen | Prevents coffee dust particles from clogging the valve seal mechanism. |
| Filter Inclusion | Optional / Rarely Integrated | Built-in Micro-Particulate Filter | Guarantees zero particle jamming, maintaining hermetic seal integrity. |
Modern global markets demand a dual focus: uncompromised barrier performance to preserve delicate flavor profiles, combined with strict adherence to environmental regulations (such as the EU Packaging and Packaging Waste Regulation and US state-level EPR laws). YPAK provides engineered custom material formulations tailored to your brand's shelf-life and sustainability goals.
Constructed utilizing high-density MDO-PE paired with EVOH-enhanced low-density PE sealing layers. This mono-material structure achieves SPI Recycling Code 4 compliance while offering Oxygen Transmission Rates (OTR) under 1.0 cc/m²/24hrs.
Derived from renewable plant starches, our compostable laminates pair Kraft Paper with metallized PLA or PBS barrier layers, certified under EN 13432 and ASTM D6400 standards.
Engineered with PET / AL / LLDPE triple-layer laminates to deliver absolute zero transmission for light, oxygen, and water vapor (WVTR < 0.05 g/m²/24hrs), guaranteeing a 24-month shelf life.
Founded in 2011, YPAK operates three facilities across Hong Kong, Dongguan, and Foshan, emerging as one of China’s leading coffee bag manufacturers. Our Foshan and Dongguan plants are BRCGS Food Safety and ISO 22000:2018 certified—ensuring every pouch meets rigorous global food contact standards with full traceability. We fit Swiss WIPF one-way valves as standard, delivering industry-leading technology for keeping coffee freshness in our packaging. Our HP Indigo 25K digital press enables MOQ-free, plate-free runs with photorealistic print quality—perfect for limited editions and market testing. With a 99.5% on-time delivery rate, we keep your production lines moving. Our recyclable and compostable pouches help you stay ahead of plastic regulations in the EU, UK, and North America—without compromising performance. You are welcome to visit YPAK.
A timeline of technological investment, facility expansion, and quality management upgrades.
In May 2012, established our first complete flexible packaging production line.
In March 2016, began manufacturing specialized box-shaped flat bottom pouches.
In August 2017, established our second high-speed packaging production line.
In April 2018, integrated eco-friendly solvent-free composite lamination technology.
Introduced the automated ink adjustment system for precise Delta-E color consistency.
Implemented enterprise-wide ERP production system for full batch traceability.
Introduced the industrial HP INDIGO 25K digital printing press system. This technology enables micro-to-medium specialty coffee brands to run short-run, multi-SKU designs without cylinder copperplate investment, maintaining 100% color matching fidelity.
YPAK guarantees transparent, precise, and reliable manufacturing execution through our structured 3-stage client management protocol.
Improve customer experience through online video confirmation: One of the keys to meeting customer needs is providing pre-sales service that builds a solid foundation for long-term relationships. We provide one-on-one service to ensure accurate, efficient communication.
Traditionally, pre-sales service involves assisting customers in selecting products and resolving issues—a process that can be time-consuming. With online video confirmation, we eliminate guesswork and provide personalized attention before tooling begins.
Maintaining total control over production: We provide exceptional mid-sale service to ensure a seamless transition from order placement to final delivery.
This involves monitoring each stage of printing, lamination, and pouch converting. We send live video and high-resolution photo updates, allowing roasters to visualize their order throughout production.
Long-term partnership assurance: Our commitment extends beyond shipment delivery. Excellent after-sales service reinforces strong brand partnerships and repeat success.
By investing in continuous staff training and structured feedback channels, YPAK guarantees prompt resolution, batch re-testing, and complete quality assurance for long-term customer satisfaction.
Clear answers regarding valve performance, MOQ, custom print options, and sustainability compliance.
Freshly roasted coffee off-gasses substantial amounts of carbon dioxide (CO2) for days post-roast. Without a valve, sealed bags will swell and potentially burst. A Swiss WIPF one-way degassing valve allows CO2 to vent outwards under low internal pressure (2-5 mbar) while preventing ambient oxygen and moisture from entering. This preserves delicate aromatics and prevents oxidation.
Traditional Gravure Printing relies on custom-etched metal cylinders, requiring high setup fees and minimum orders of 10,000 to 20,000 pouches per SKU. Our HP Indigo 25K Digital Printing operates without physical cylinders, enabling multi-SKU runs, variable data printing, and fast turnarounds with zero cylinder charges—ideal for limited-edition roasts and seasonal releases.
Yes, YPAK offers two distinct eco-friendly material lines: 1) 100% Recyclable Mono-PE Pouches (SPI Code 4 compliant) engineered with high-barrier EVOH layers. 2) Industrial & Home Compostable Pouches made from Kraft paper and certified PLA/PBS matrices meeting EN 13432 standards. Both options can be fitted with matching recyclable or compostable degassing valves.
Since 2018, YPAK has utilized 100% solvent-free composite lamination technology across our facilities. Unlike conventional solvent-based adhesives that leave residual Volatile Organic Compounds (VOCs), our solvent-free process guarantees zero chemical odor migration, ensuring your coffee aroma remains unadulterated.
We manufacture a full range of formats, including Flat Bottom Box Pouches (5 panels for branding), Stand-Up Pouches with Resealable Zippers, Side Gusset Bags (Quad Seal or Lap Seal), Flat Pillow Bags, and Single-Serve Drip Coffee Filter Bags. Tactile finishes include Rough Matte, Soft-Touch Matte, Gloss Spot UV, and Metallic Foil Hot Stamping.
Our main manufacturing facilities in Foshan and Dongguan hold BRCGS Food Safety (Grade AA) and ISO 22000:2018 certifications. All raw materials conform strictly to US FDA 21 CFR 177.1520 and EU Regulation (EC) No 1935/2004 for direct food contact.
